Picking the Right Clustering for MySQL: Cloud-only Services or Flexible Tungsten Clusters? New webinar-on-demand

As businesses head into the cloud, it is tempting to reach for the first product that offers to make database operation as simple as punching a few buttons on a menu.  However, there’s a big difference between firing up cloud database services such as Amazon RDS for testing or development and finding a solution that can handle hundreds of millions of transactions daily. 

This webinar-on-demand explores how your business can benefit from Continuent Tungsten, a flexible clustering solution that helps data-driven businesses handle billions of transactions daily across a wide range of environments.  We’ll focus on the following problems in particular: 

  • Ensuring fully capable cloud DBMS operation  
  • Avoiding lock-in by choosing solutions that run across clouds as well as on-premises  
  • Spreading MySQL data over regions using flexible primary/DR and multi-master topologies
  • Controlling maintenance intervals and the DBMS stack directly
  • Integrating in real-time to data warehouses and on-premises DBMS like Oracle  
  • Ensuring immediate access to top-notch, 24x7 support when things go south 
Your data is too precious to take shortcuts.  Learn how you can use Continuent Tungsten to build scalable management solutions that offer the economic benefits of the cloud with the enterprise capabilities required by businesses that live and die by their data.

Continuent Tungsten 2.0.3 Release Notification
We are pleased to inform you that the new Continuent Tungsten 2.0.3 is now available. This is a recommended release for all Continuent Tungsten clustering customers as it contains important updates and improvements to the stability of the manager component, specifically with respect to possible stalls and memory usage that would cause manager failures:
  • A number of fixes to the Manager failure detection and recovery logic to improve stability
  • Improvements to the Connector Bridgemode, default Bridgemode buffer sizes, and connection management to improve performance and memory usage
  • Updated recommendations for witnesses and member calculations to ensure correct quorum determination
  • Within Composite Clusters (multiple geographically distributed clusters working together), inter-cluster communication now requires TCP/IP port 7 to be open to ensure availability and stability.
For a complete listing of new features and improvements in Continuent Tungsten 2.0.3, see release notes.

New webinar-on-demand: Geographically distributed multi-master MySQL clusters
Global data access can greatly expand the reach of your business. Continuent Tungsten multi-site multi-master (MSMM) solutions enable applications to accept write traffic in multiple locations across on-premises and cloud providers. This includes the following important real-world use cases:
  • Improve performance for globally distributed users registering hardware devices by permitting updates on the geographically closest site.
  • Ensure availability of credit card processing by spreading transaction processing across two or more sites. Users can still process credit card transactions if a single site is unavailable to them for any reason, including end-user Internet routing problems.
  • Enable business continuity by using multi-master updates on different hosting providers for service scalability, personalization and software upgrades of GPS devices.
Individual Continuent Tungsten clusters already provide excellent single-site database availability and performance. In this webinar-on-demand we review the benefits of combining multiple Continuent Tungsten clusters into a global multi-site multi-master topology for:
  • Optimizing your installation for MSMM
  • Optimizing your application for MSMM
  • Monitoring and administration
  • Failover and recovery of individual servers or entire locations.

Harnessing the power of master/slave clusters to operate data-driven businesses on MySQL

Users seeking high availability, DR and zero downtime maintenance operation for business-critical MySQL applications face confusing choices. Is multi-master or master/slave clustering better?  What about synchronous versus asynchronous replication? Using a plain vanilla, stock MySQL or a modified version of it? Which of these choices are right for data-driven businesses that depend on fast, reliable data access?

This no-BS webinar-on-demand cuts through the FUD to explore the real trade-offs between the different clustering and replication methods, then show you how Continuent Tungsten asynchronous master/slave clusters support these important capabilities for business-critical applications:

  • High application write rates
  • Mixed workloads consisting of large and small transactions
  • Data across multiple geographically distributed locations
  • Failures and more importantly recovery from them
  • Zero downtime maintenance and software upgrades
  • Use of off-the-shelf MySQL/MariaDB to avoid application changes and allow clusters to improve as MySQL itself does
We will illustrate key points with demonstrations and case studies from deployed systems.  Click here to view this educational session on the cutting edge of MySQL data management!
